Sector Protection/Unprotection
The hardware sector protection feature disables both
program and erase operations in any sector. The hard-
ware sector unprotection feature re-enables both
program and erase operations in previously protected
sectors. Sector protection/unprotection can be imple-
mented via two methods.
The primary method requires VID on the RESET# pin
only, and can be implemented either in-system or via
programming equipment. Figure 1, on page 11 shows
the algorithms and Figure 21, on page 33 shows the
timing diagram. This method uses standard micropro-
cessor bus cycle timing. For sector unprotect, all
unprotected sectors must first be protected prior to the
first sector unprotect write cycle.
The alternate method intended only for programming
equipment requires VID on address pin A9, OE#, and
RESET#. This method is compatible with programmer
routines written for earlier 3.0 volt-only AMD flash
devices. Publication number 22134 contains further
details; contact an AMD representative to request a
copy.
The device is shipped with all sectors unprotected.
AMD offers the option of programming and protecting
sectors at its factory prior to shipping the device
through AMD’s ExpressFlash Service. Contact an
AMD representative for details.
It is possible to determine whether a sector is protected
or unprotected. See “Autoselect Mode” on page 9” for
details.
Temporary Sector Unprotect
This feature allows temporary unprotection of previ-
ously protected sectors to change data in-system. The
Sector Unprotect mode is activated by setting the
RESET# pin to VID. During this mode, formerly pro-
tected sectors can be programmed or erased by
selecting the sector addresses. Once VID is removed
from the RESET# pin, all the previously protected
sectors are protected again. Figure 2, on page 12
shows the algorithm, and Figure 20, on page 32 shows
the timing diagrams, for this feature.
